Abstract
The cruise was a part of the Centre of Excellence for Gas Hydrate, Environment and Climate (CAGE) at UiT – The Arctic University of Norway. The cruise aimed at investigating areas with gas venting from the seabed in outer Storfjordrenna and central Bjørnøyrenna. More specific objectives were: sampling benthic seabed fauna in areas of gas venting to investigate the biological responses to natural gas seeping, mapping seafloor geomorphology and subseabed structures relations to gas venting, and mapping seafloor imprints of deglaciation.
